I'm trying to find port length for a round port. Using the calculations for diysubwoofers.org, for a 1" port, I get a 2.882088858" port lenght, however, using winisd alpha, I get a 4.53" port length. Is the winisd calculation for port length wrong or am I?

Seeing how we don't know the net volume of the enclosure, there is no way we can tell you what is correct.

What application would you be using a single 1" diameter port?

Oh my bad. I knew to include that, but slipped my mind.

0.250 net @ 40

It's for a 6.5" midbass in door pods, and I'm considering porting 'em, but am trying to find length to determine if the depth will be too great.

looks like I missed a decemial point in my excel spread sheet (work in progress... heh). min diameter looks to be 4.25"
